Knuckle cracking doesn't "crack" a joint. The sound comes from gas bubbles bursting in the fluid inside the joint. While knuckle cracking is mostly harmless, other types of noises or the presence of pain can indicate a more serious joint problem.

Osteoarthritis in the hand is a painful condition that is more common in women than in men. While this condition can be debilitating, a number of strategies can be used to manage it, including using various topical, oral, and injected pain medications; splinting the joint; making lifestyle changes; and working with a hand therapist. Surgery may be an option when other measures have failed to control symptoms.

Experts suggest people replace their walking shoes every 300 to 500 miles.

Many conditions affect the feet and can cause pain. Five common problems are bunions, fallen arches, hammertoes, ingrown toenails, and plantar fasciitis. Fortunately, there's a wide range of treatments for relief. New approaches include stretching the calf muscles to improve the way feet fit into orthotic insoles; shock-wave treatment for plantar fasciitis; and minimally invasive surgeries for bunions and hammertoes that involve small instruments and incisions. Tried-and-true therapies include soaking feet when an ingrown toenail causes pain, or wearing a splint at night for plantar fascitis.

Platelet-rich plasma injections are used to reduce pain and speed healing for a number of common problems that affect the tendons, muscles, and joints, ranging from arthritis to shoulder pain.

There is some evidence that it may be effective for lateral epicondylitis (tennis elbow). People should consider whether there is a better option before undergoing PRP injections.

The first-ever guidelines to diagnose chest pain document the range of possible heart attack symptoms. They include a sense of pressure, tightness, squeezing, or heaviness in the chest but also in the shoulders, arms, neck, back, upper abdomen, or jaw. The report also provides a road map to help doctors assess chest pain with selective use of the latest available tests. Chest discomfort can also result from other conditions that affect the heart (such as pericarditis) and nearby organs. These include acid reflux, muscle or joint issues, and lung problems.
